Answer:
A. The distribution should be skewed to the left because the mean is less than the median.
B. Most students scored a C or higher.
Step-by-step explanation:
A. Since mean<median<mode, we have a negative skewness and hence the distribution is skewed to the left.
B. Since the mean score is 71 and the modal score is 81, it is expected that a 'C' should be the lowest grade most students will have.
Answer:
3/4 or 0.75
Step-by-step explanation:
the equation is in slope-intercept form
y=mx+b
where m is the slope and b is the y-intercept.
you have already found the y-intercept to be -2, so now we just have to find the slope.
slope is also known as rise/run. so if we start at the y-intercept of -2, we can rise (go up) 3 units and then run (go over) 4 units until we reach another point on the line.
so the slope is 3/4 which is also equal to 0.75 units
8x^4y^213. I personally cannot figure out the numerator and denominator, sorry :)
